CVE-2025-10066 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the itsourcecode POS Point of Sale System. The vulnerability resides in an unspecified function within the file /inventory/main/vendors/datatables/unit_testing/templates/dymanic_table.php. The issue arises from improper sanitization or validation of input parameters, specifically the 'scripts' argument, which allows an attacker to inject malicious scripts. This vulnerability can be exploited remotely without requiring authentication, and user interaction is necessary to trigger the malicious script execution, typically through a crafted URL or input field. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level. The vector details show that the attack vector is network-based (AV:N), requires no privileges (PR:N), no authentication (AT:N), but does require user interaction (UI:P). The impact primarily affects the integrity and availability of the application, with limited impact on confidentiality. The vulnerability does not involve scope changes or elevated privileges. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The affected component is part of the POS system's inventory management module, which is critical for retail operations. Successful exploitation could allow attackers to execute arbitrary scripts in the context of the POS system's web interface, potentially leading to session hijacking, defacement, or redirection to malicious sites, thereby undermining trust and operational continuity.

For European organizations using the itsourcecode POS Point of Sale System version 1.0, this vulnerability poses a moderate risk. The POS system is integral to retail and hospitality sectors, which are significant in Europe. Exploitation could lead to unauthorized script execution, enabling attackers to steal session tokens, manipulate displayed data, or redirect users to phishing sites. This could result in financial losses, reputational damage, and regulatory scrutiny under GDPR if customer data is indirectly compromised. The vulnerability's remote exploitability without authentication makes it a viable attack vector, especially in environments where POS systems are accessible over internal networks or exposed web interfaces. Given the critical role of POS systems in transaction processing, any disruption or compromise could impact business continuity and customer trust. However, the lack of known active exploits and the medium severity rating suggest the threat is moderate but warrants timely remediation to prevent escalation.

1. Immediate application of patches or updates from itsourcecode once available is the most effective mitigation. Since no patch links are currently provided, organizations should monitor vendor advisories closely. 2. Implement input validation and output encoding on all user-supplied data, particularly in the affected PHP file and related modules, to neutralize malicious scripts. 3. Employ Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads targeting the POS system's web interface. 4. Restrict network access to the POS system's management interfaces, limiting exposure to trusted internal networks only. 5. Conduct regular security assessments and penetration tests focusing on web application vulnerabilities within POS environments. 6. Educate staff to recognize phishing attempts that might leverage this vulnerability to deliver malicious payloads. 7. Monitor logs for unusual activities or repeated attempts to exploit the 'scripts' parameter in the affected endpoint. 8. Consider deploying Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks by restricting script sources.
